To all whom itlmay concern Be it known that I, Jesse S. RODENHI, a

siding in the city, county, and State of New York, have invented.certain new and useful Improvements in Carbon Binders and Fillers, ofwhich the following is a specification.

The carbon binder which is the subject of this invention consists of aflexible back having an end and a side flap adapted to be folded over toform a pocket to receive the ends of the carbon sheets, the end flaphaving, a'central tongue on each side of which are tabs secured to theback, the end flap be-I ing slotted to receive the tabs. In thepreferred form of the device the flap at one side, shown as the left, isof a length greater than the depth of the pocket, 2'. e., the width oftheend flap at this point, so that it ex tends along the lateral edge ofthe back beyond the end flap and serves not only to hold the edges ofthe carbons, but holds and 7 positions the lateral edge of the papernear,

the end. At the other side I have shown a flap made of a length aboutequal to the width of the end flap orthe depth of the pocket, so thatthis side flap does not project 1 beyond the pocket and merely engagesthe carbon. Thus the paper is held on two sides only and may be easilyremoved. This flap is not entirely essential to the operation of mydevice and may be omitted. Thepoint of attachment of the tabs to theback is sub stantially opposite the edge of the endflap, and these tabsare'passed over the edge of that flap and inserted into the pocketthrough the slot provided therefor. The carbon sheets used are of awidth but slightly less than that of the binder'and incidentally of thepocket.

In assembling the device for operation,

the carbon sheets, which are slotted to receive the tabs, are firstlaidupon the back,

I the tabs being passed through the slots in thercarbon sheets. The sideflaps are then folded over the edges of the carbons, and the end flap isfolded down upon the carbons and upon the side flaps. The tabs are thenfolded over the edge of the end flap and inserted in the slots therein.The paper upon which the carbon copies are to be made is then insertedbeneath the'sheets of carbon,

the side flap which I have described as projecting beyond the pocket,serving to posiferred form.

tion thev paper at-that side and the tabs serving to position it at theend. The tongue on overlies the carbon and paper, servlng to eet Vldtheni In positioin The s upon which the original writingis done islaid on "top of th p p e topf'carbcmv and inserted beneath the slde flapand-the tongue, resting sitioned laterally by the fold ofthe side and;at its end by the edges of the end flapad ac'ent the base of the tongue.The-carbon sheet of my filler, is made with slots to receive the tonguesas described. These slots are provided at bothends of the sheet so.

that when itbe'comes worn in one position, the sheet may be reversed andused from the other end. I

At the sides of the carbon sheets adjacent the e nds,or' on the endedges ifpreferred, I provlde 'thumb-notches, the back beingcorrespondlngly notched. ,I am thus able to remove the copy paperwithout handling the carbon sheets. l v

In operation, the binder with the filler, assembled as described, isinserted in' the machine 1n the manner in which the single sheets or anumber of sheets accompanied by the carbons are ordinarily inserted.

It will be apparent that the binder, which is the subject of myinvention, except for the thickness of the back sheet, is no more bulkythan would be the same number of free carbon sheets with the necessarysheets of paper. Atthe same time, the carbons are held in registrationso that they are ready to receive the copy paper which can be quicklyand uniformly adjusted. Any number of copies may be made and withdrawnfrom the binder without touching or disturbing the carbon sheets.Thereby there is a great resulting economy of time, because with thefree carbons, such asare now used, the copy cannot be withdrawn frombetween the carbon sheets, but each piece of carbon and copy must behandled separately or copy shaken out from between the carbons to theresulting deterioration of the latter.

In the accompanying drawing. I have shown a carbon binder with thefiller madein accordance with my invention in. its pre- Figure l is aplanlidevice. 2 is a fragmentary longitudinal section pn the line 2, 2of Fig. 1. Fig. 3 is a'similar-section showing the device partlyassembled. Fig. 4 is a fragment-ary'plan of a carbon sheet made inaccordance with my invention.

The binder consists of a flexible back sheet 1, having an end flap 2, aside flap 3 of a length greater than the width of the adjacent portionof the end flap, and in the preferred form of myinvention there isanother side flap 4 of a length substantially equal to the width of theadjacent portion of the end flap. The side and end flaps, as shown,arefolded over on one side of the back sheet to form an end pocket, theside flaps bein first folded in and the end flap being olded down uponthe side flaps. Formed centrally of the end flap is a tongue'5, andsecured to the back near each side of the tongue is a tab 6. These tabs,in operative position, are folded over the edge 7 of the end flap andtheir ends are inserted into the pocket through slots 8 in the fiap.

The carbon paper or filler 15 to cotiperate with, my binder, a sheet ofwhich is fragmentarily illustrated in Fig. 4, is provided with slots '9to receive the tabs 6 and is notched at 10 so that the copy paper may beinserted and removed without interfering with the bound carbon sheets.The back is correspondingly notched at 11. Preferably the carbon sheetsare formed at both ends, as shown at Fi 4, so that the sheets may bereversed an uniformly exhausted. The carbons may also be notched at theends as at 12 with the back correspondingly notched at 13.

The manner of assembling my binder will be apparent from the descriptionand preamble. The back sheet is first laid flat, as shown in Fig. 3. Thecarbon sheets are placed in re istration and laid on the back sheet, theta s 6 being passed through the corresponding slots. Next the side fla s3, 4 are folded over upon the sheets and t e end flap 2 is folded overthe side flaps, inclosing the ends of the carbon sheets. The tabs 6 arethen turned over the edges of the end flap and inserted in the slots 8.The copy paper 14 is inserted one sheet beneath each carbon sheet, itsends being positioned by hearing against the tabs 6, and its side edgenear the end taking a bearing in the fold of the flap 3. The originalsheet, which is placed on top of the top carbon, also takes a caringatits side edge in the folds of the flap 3, and at its end against theed e of the end flap adjacent the tongue 7. The latter rests on the topface of the top sheet, holding it in position. It will be apparent thatwhen thus assembled, the binder and filler may be put through themachine as easily as a single sheet, and that the copy sheets may bequickly and conveniently removed and replaced without disturbing thecarbons. This is done with a great resulting economy of time andmaterials.

I have thus described in detail the preferred embodiment of my inventionin order that its nature and operation may be clearly understood.However, the specific terms herein are used in their descriptive ratherthan in their limiting sense and the scope of the invention is definedin the claims.
